  • Patent number: 10947658
    Abstract: A washing machine appliance and a method of selectively draining a sump of the washing machine appliance at the start of an operating cycle is provided. The method includes determining that the drain pump assembly has drained wash fluid from the sump, e.g., by checking to see whether an empty sump flag has been set in the controller. In addition, the method includes determining that a water supply valve has not been opened since the wash fluid was drained from the sump and that a sump pressure exceeds a predetermined threshold pressure, e.g., indicating that water is in sump that was not intentionally added by the water supply valve. The drain pump assembly is then operated to perform a drain cycle at the beginning of a subsequent operating cycle.

  • Patent number: 10927539
    Abstract: Apparatus and a method for cleaning accumulated sediment from storm drain conduits and other large-diameter conduits. A nozzle assembly is arranged to deliver a high-volume flow of water at a pressure high enough to loosen sediment from the interior of a conduit and to propel the nozzle assembly and an associated nozzle feed hose upstream within a conduit being cleaned. Water from the nozzle assembly flushes the sediment downstream and is then collected, partially cleaned, and reused in the nozzle assembly. Mud and clay may be left in the water to increase its specific gravity and viscosity. A self-contained portable and mobile system includes a tank and apparatus for removal of high concentrations of entrained or suspended solids, and a pump and conduits for delivering a high-volume flow of water, containing quantities of suspended solids, to the nozzle assembly.
